. T0 all whom, it may con/cern: v

vember 11, 1902, by providing-- means operat-Y ing as an adjunct to thetrimming-knives for cutting o the superfluous end of the'shaderollstick.

` A further object is to provide means'whereby4 the operator' can easilydetermine the proper amount to be cut-from the endof the stick.

Other objects of the invention will appear lfrom the followingdetailedde'scription.

The invention consists generally in providing a saw in connection withthe cloth-trim- 1v ming mechanism. Y

urther, the invention consists in providing meansV for rendering the sawoperative or inoperative, as desired; and, further, the inventionconsists in a suitable gage device by means of which the desired amountto be cut from the end cf the stick can be easily and quicklydetermined.

. Further, the invention consists in various constructions andcombinations, all as hereinafter described, and particularly pointed outin the claims.

In the accompanying drawings, forming part of this specification, Figurel is a plan view of my improved shade-roll trimmer. Fig. 2 is alongitudinal section of the same. Fig. 3 is a transverse section on theline a: a: of Fig. 1.y Fig. 4 is a v'iew looking at the rear of thetrimming mechanism, the supportinghub for the -revolving member beingshown in section.

Fig. 11 .is a detail of the saw, showing the 55 means provided forpreventing rotation thereof on its axis.

2 and is secured thereto byscrews or any A gear 6 is provided thereon bya ring 8, that is secured to the outer end-of said h ub and isconntersnnk in the face of said disk and permits the revolution of thediskoh the hub, while preventing their accidental separation.

disk is provided upon each side of the hub- ,opening with guideways 9,wherein blocks 10 are slidable Yand normally projected toward theopening 4 by springs 11.' Knives 12, having, preferably, V-shapedcutting edges, are 75 mounted on the blocks 10 and are normally heldprojecting partially across the opening 1 by the yielding pressure ofsaid springs. The blocks 10 are provided also,

preferably on the side opposite the knives, 8o

with stops 13, having beveled edges 14, that are in position to beengaged by the corresponding faces 15 of lugs 16, provided on a ring 17,that is revoluble on the hub of the disk 7 between itand the gear 6.

erator can partially rotate said ring, move the beveled faces 15 intoengagement with the corresponding faces on the stops 13, sepa- 9o ratethe knives against the tension of the springs 11, and withdraw them fromthe open ingli to allow of insertion of the end of a shade-roll therein.After the insertion of the roll the knives are lreleased by a reverse 95I Y Patented Maly 127 190:3".2 l Y The revolving 7o This 35 ring 17 ispreferably provided with an operating-handle 18, by means of which theop- All this mechanism, however, is roo make no claim to the same hereinexcept in combination with the novel features as hereinafter described.

Itis desirable after the cloth is trimmed to provide some means forcutting o the end of the stick, which has been usually done by a handsawnot connected with and operating entirely independent of the trimmingmechanism. To perfect the trimmer and torender its operation complete, Iprovide a yoke or frame 19, having a stud on one side tting within anopening in the revolving disk or member 7, near the circumferencethereof. A handle 2l is provided on the yoke 19, and a lug 22 isprovided on the stud 2O and normally holds the stud against forwardmovement, but when opposite a certain predetermined point in itsrevolution willenter a slot 23 in the revolving member and allow thestud and yoke to be drawn forward, as shown in Fig. S. Ashaft 24 iscentrally mounted in said stud and projects forward through the yoke 19and into said handle, and upon the rear end of this shaft a pinion 25 ismounted in position to engage the teeth of the stationary gear 6 and bemoved out of engagement therewith by the forward movement of Saidstud. Agear 26 is mounted on the shaft 24 within the frame 19, meshingzwith apinion 27, mounted on a bolt 2S and carrying a circular saw 29 on itshub.

From the foregoing it is evident that when the member 7 is revolved andthe pinion 25 is in engagement with the teeth of the stationary gearsaid pinion, in addition to its movement around the circumference ofsaid stationary gear, will also revolve with the shaft 24, which in turnwill drive the gear l26, the pinion 27, and the circular saw 29.

The saw is arranged outside the trimmingknives any suitable distance,preferably about three-eighths of an inch, and during the operation ofthe knives will be out of gear and inoperative, as shown in Fig. 8. Whenthe saw is not in use, it is swung around out of the path of theshade-roll by the tension of a spring 30, connecting the yoke 19 withthe revolving member. (See Figs. 6 and 7.) In the rear of the trimmingmechanism upon the board 2 I provide a support or rest 3l for the roll,and along the middle of said board I arrange a plate 32, provided with ascale 33, the board beneath said scale having a recess or slot 34,wherein a gage 35 is movable, being adjustably secured to the plate 32by a set-screw 36. The marks upon the scale represent inches and feetand will enable the operator by adjusting the gage to very easily andquickly ascertain how much to cut off the .end of the stick to obtainthe desired width of shade. A plate 37 is preferably secured to theboard 2, having a circular socket 38, wherein the end of the shadestickmay be thrust to adj ust the edge of the cloth preparatory to trimming.

Instead of using the knives having V- shaped edges, as heretoforedescribed, I may provide circular knives 39, mounted on pivots 40between the brackets 41 and the reciprocating blocks l0, these kniveshaving circular cuttin g edges that engage the cloth to trim the same,and I prefer to provide three of them and a correspondingnumber ofguides 9 and blocks l0 in the revolving disk,

provide a longitndinal'slot` 43 therein to receive a lug 44, provided onthe saw', that will permit adjustment of the saw longitudinally on thehub, but prevent its revolution independently thereof. The saw is lockedin any desired posit-ion on .thehub by means of the lock-nuts 45.By'loosening these nuts the saw can be adjusted toward or from theknives and the length of the cut at the end of the stick varied asdesired.

The operation, briefly, of my improved shade-trim mer is as follows: Theknives having been-separated and withdrawn 'from the hub-opening, theend of the shade-roll-is inserted therein, with the opposite endsupported upon therest 31 in a horizontal position. the proper amount tobe trimmed, and the knives are then released, allowing them to fly backand engage the cloth. The disk or member carrying the knives is thenrevolved and the desired amount trimmed from the edge of the cloth.During this time the saw hasbeen ont of gear and inoperative. As soon,however, as the cloth is trimmed the saw is thrown into gear, therevolving member set in motion again, and the end of the stick quicklyand neatly cut 0K.
